Importance Of Aez In Sustainable Agricultural Development Planning

The ability of the world's natural resources to provide for the needs of its growing population is a fundamental issue for the international community. World's population is increasing rapidly and at the same time, essential natural resources, such as land and water, are declining both in quantity and quality due to such factors as competition with industrial and urban demands. The basic problem is that limits to the productive capacity of land resources are set by climate, soil and land forms condition. In this context AEZ can be regarded as a set of applications, leading to an assessment of land suitability and potential productivity in terms of climate, soil and land forms condition.

Agro-Ecological Zoning (AEZ) is one of the most important bases of sustainable agricultural development planning of a region. It is applicable in micro or local level planning mainly for rainfed agriculture. It assesses basically the yield potentialities of various crop conditions; evolves future plan of action involving crop diversification; determines suitability of different crops for optimizing land use, disseminates research results and agro-technology. As a result sustainable agricultural development planning is increasingly being based on agro-ecological zones. In this process agro climate zoning has become very popular (Verma and Partap, 1989). The initial focus of the FAO agro-ecological zoning system was to assess the suitability of different types of land use for selected land uses. It is an important starting point for selected land use planning with an overview of the whole region. It diagnoses the present situation with regard to farming and land use by categorizing, describing and analyzing, farming systems components.
